This category is for sites relating to the debate of whether to change the Australian flag, including sites both for and against a change, and sites that propose new flag designs. Although the debate is mainly about the Australian national flag, some would also like to change state and territory flags, as well as ensigns and civil flags.

Sites that primarily provide reference material on current or past Australian flags, and do not focus on the flag debate or presenting new flag designs, belong in Reference: Flags: Regional: Australia.
